The Nickel Boys: A Novel by Colson Whitehead:
Mr. Hill maintained a broad collection of bow ties: polka dot, bright red, banana yellow. His wide, kind face was somehow made kinder by the crescent scar over his right eye where a white man had slugged him with a tire iron. “Nashville,” he said when someone asked one afternoon, and he bit into his pear. The class focused on US history since the Civil War, but at every opportunity Mr. Hill guided them to the present, linking what had happened a hundred years ago to their current lives. They’d set off down one road at the beginning of class and it always led back to their doorsteps.
